GRAIN-SHOCKER.

Specification of Letters Patent. Patgntgd J l 13 lggql Application filed April 4, 1917, Serial No. 159,614. Renewed December 4, 1919. Serial No. 342,475.

To all whom it may concern:

Be it known that we, Gnonon hints and T canes H. PRALL, citizens or the United States, and residents of Philadelphia, Pennsylvania, have invented certain Improvements in Grain-Shockers, or" which the following is a specification.

Our invention relates to grain shocking devices; and the object of our invention is to provide a structure arranged to travel with the harvester and binder, and in such relation to the binder that the mechanism carried by our improved shock forming structure lies in proper position to pick up bundles from a platform to which they are delivered by the binder and present the same to a suitable bundlecarrying basket or crib suit-ably connected to the rear of our improved structure in which the shocks, subsequently deposited upon the ground, are formed.

Our invention includes a frame with sui able running gear whereby it may traverse the ground; such running gear providing the necessary power to operate the bundlegripping and lifting mechanism, and mechanism to actuate the crib or basket in which the shock is formed to its receiving position.

At the forepart of the supporting frame to which the running gear is attached, a vertical "frame is provided to which connected the bundle-lifting means whereby bundles or sheaves may be transferred from the platform to the crib or basket.

These and other features of our iuvention, including the various details embodied in our improved apparatus, are more fully disclosed hereinafter, reference being had to the accompanying drawings, in which:

lligure 1, represents a plan view of our im n'oved shocking machine.

Fig. 2, is a side elevation of the same showing the crib or basket in the raised or active position ready to receive bundles or sheaves; the mechanism for lifting the lattor from the platform being shown in the position assumed after delivery of the bundles or sheaves to said basket. 7

Fig. is a similar elevation showing the bundle-gripping mechanism in picking-up position. l

Fig. 4, is a front elevation of the machine,

partly in section, on the line lVlV, Fig. 2.

Fig. 5, is a vertical sectional view'on the line V-V. 2, looking toward the rear of the machine.

Fig. 6, is a sectional view illustrating a detail or our invention.

Fig. 7, is a view of a modified detail within the scope of our invention.

Fig. 8, is a sectional view on the line VIII- VIII, Fig. 7, and F igs. 9, l0 and ll, are diagrammatic views illustrating the manner in which a pair of bundles or sheaves are handled.

The running gear and frame, which may be rectangular in plan view, comprises side members 1, with suitable cross-bars 2, connecting the same; a shaft or axle 3, being provided, suitably hung in bearings carried by the frame, and having wheels l, at its opposite ends; one or both of which may be provided with spurs 5', to increase the traction. The forward end of the frame is preferably provided with a bearing 6, for a bracket 7, carrying a caster wheel 8.

At the rear of the running gear or frame, we provide a crib or basket 9, having connecting members 10, which are coupled to the running by links 11. The basket or crib may be maintained in the elevated position, as shown in 2. 8 and 5, by means of a link arm 12, which may be. arranged to overlie a counter-shaft 13, which may be mounted. directly over the 3; said lever being connected at its free end to a chain is, lying in engagement with a toothed segment carried by the shaft 13; which segment in turn is operatively connected with a torsion spring 16, on said shaft; having its opposite end connected at 17 to a portion of: the frame. The torsion spring operates to restore the crib or basket to the elevated position through the mechanism indicated, after a load or bundles or sheaves constituting a shock has been deposited upon the ground.

A. shown in Figs. 3 and 5, the basket is retained in the position indicated by reason of the fact that the link arm 12, is bent so that its end in coimectirm with the chain 1%, extends past the cen around which said chainmoves. To overcome this condition, we provid a connection in the form or" cord or chain 15, attached to a pulley 15*, secured to the shaft 13, and attached at its opposite enc. to a lever (not shown) convenient to theoperator or driver of the harvester. i

lit the front of the running gee r frame, a vertically disposed frame 18, is provided, comprising side memberslQ, connected at bars of this frame are preferably braced from the running gear frame by struts 22, which may extend forwardly beyond the front of the frame 18, and provide a supper 1 for a shaft or bar 23, for a purpose to be described; additional supporting and bracing means for said shaft 23, extending from the vertical. frame in the form of bracket struts 24.

Carried by the axle 3, of the machine is a gear wheol.25, which may be thrown into and out of operative engagement by a clutch, 26, so as to be driven by the axle when do sired, and this gear wheel mesh with a horizontally disposed gear wheel Q7, suitably journaled on the running gear frame 7 and serving as a face plate or pitman to operate a bevel gear segment '28, which may be horizontally movable on a vertical axis 29; a connecting bar 30, extending between the same and the operating gear wheel 27;

"' said gear segment 28, meshing with a gear l segment or wheel 31, on a horizontal shaft indicated at 34%, comprise rod or bar or spindle 82, and to which gear segment is attached a connection for a substantially basket is to be' filled may be properly operated. i

The means for lifting the bundles or sheaves from the platform of the shocker,

as W,

' connected by means of a universal joint 36,

' neath the rod are a pairof supports 49,

to the shaft 23, at the front of the machine; said rod or bar 35, being adapted to slot 37, in the plate 20, carried by tical frame 18, and being actuated the lifting and depositing operation by the rtically movable'member 33, controlled by oevei gear wheel or segment 51 the verymovable member-38, having a slotted tic upper end 58, through which said rod 35,

passes. 'The outer or free end of the rod 35, carries a hub 10, in which is mounted a hollow stem 4 1, carrying bracket rrame 12, ext idin beneath the rod and upon which is jouri .der a pinion d3, eiwaged by a rack 14, for a purpose to be. d .bed.

Bepending from the bracket frame 42 be- I for looked arms 50, the position of which may be relatively fixed with respect to the rest of the structure. In addition, the bracket framecarriesopen frames 51, which, additionally, may be connected together the center by a bolt 52, on which is ourn'a'led I l a bellcranklever 53.

The forward ends of the hooked bars 50,

are connected together at 54, and pivotally connectedto said hooked bars 50, at the to effect sition to descend. upon and grasp a pair of sheaves or bundles. in this act, the ends of the hook arms 56, contact with the platform 34, and releasethemselves from the engagement of the lugs 59, of the frames 51. At

the same time the movement of the bar I 4 u c o I 7 to carry this oundlediiting mechanism into grasping position hasmoved with reference to a sleeve 60, slidable thereon, to which is attached at 61, a cord 62, passing around a sheave 63,at the end of the rod; the opposite end of said cord being attached at 64, to the bell crank lever 53, thereby lifting said bell crank lever so that the hook "655, may ongage the same and support it against the tension of the spring 66, until the hook arms 56, are released. Immediately they more leased, as before described, the spring 66,

which is connected to the loops attached at 68, to the arms 57, actuates said arms 57, to cause the arms 56,to be thrown in at their rear ends and thereby. grip the bundles picked up.

When the bundle gripping device is moved to pickingnp position and into engagement with the platform 34, as shown in Fig. 3,

an extensible rod 69, which is connected at one end to the sleeve 60, and at the opposite end to thevertical frame 18, and" contains a compressible spring 70 within a sleeve 71, elongates under tension of the spring 66; the latter being connected to the sleeve 60,

by means of the cord 62', and bell crank lever 58; such elongation contracting the spring 70,, When the bar 35, rises with the bundlelifting device'in engagement with sheaves lifted from the platformBd, which action swings the bundle-gripping devices to the delivery position shown in Figs. 1 and 2, the spring 70, within the'sleeve 71, 0f the rod 69, lengthens and takes up all slack of said rod between its connections. with the end frame 18, and the sleeve 60. f V

As the bundle-gripping means-are raised by the vertically movable member 33, which operates the rod 35, the pinion 43, will be turned by its engagement with the rack 14, to an extent sufficient to reverse the position of the bundle-gripping means and cause the stem-of the hook .65, toswing its projecting cnd72, into engagement with alug'73, carried by the rod 35, thereby releasing or spreading the bundle-gripping mechanism when the latter is in the position shown in Fig. 2. This rod 35, is restrained from excessive movement by means of a spring 75, connected to the same and to the vertically movable member 33, which operates it, and the latter is provided with a spring 76, between a collar 77, carried thereby and a sleeve 78, slidable horizontally on the crossbar 21, of the vertical frame 18; said sleeve 78, having another sleeve 79, pivotally connected thereto, through which the vertically movable member 33, is free to slide in its movements.

As shown in Fig. 4, the rod 35, is disposed in the curved slot 37, in the plate 20, carried by the vertical frame 18, at the front of the machine; the vertically movable member 33, being shown in the position it assumes when its connection with the gear wheel or gearsegment 31, moves in the direction of the arrow if further movement of said member 33, occurs, the rod 35, will be lowered in the left'hand portion of the slot 37. Upon the return movement of the gearsegment 31, in the direction of the arrow 31, the member 33, will be raised, lifting the rod 35,

until a roller 30, carried by saidv member" entersa notch 81, in the plate 20, which serves as a hearing or fulcrum point for the same so that the rod 35, may be swung to the opposite side of the slot 37, and upon continued movement of the gearesegment in the direction of the arrow 3 the rod 35, will be carried down the right-hand portion of said slot 37, and in such movement lower the bundle-gripping device to the platform 34, to pick up bundlesor sheaves for subsequent delivery to the basket or crib 9, in which the shocks are formed.

As the rod 35, lowers in the right-hand portion of the slot 37, the'spring rod 69, elongates, and through the medium of the cord 62, tension is applied to the spring 66 through the bell-crank lever 53, so that the moment the hooks 56, are displaced from the retaining lugs by the engagement of such hooks with the platform 3t, they will be drawn in by the operation of said spring 66, to grip the bundles or sheaves and hold them in the position shown. in Fig. 10.

in lieu of the mechanism for lifting the basket, illustrated in'Figs. 1, 2 and 3, in which a lever 12, and chain 14:, are shown in engagement with a toothed segment 15, carried by a shaft 13, we may provide the structure shown in Figs. 7 and 8, in which a segmental sheave 85, having a hollow center 86, is shown. lnthis instance, a chain H is shown as connected at 87, to the basket; thence passing through the hollow portion of the segmental sheave and being connected at 88.. to one end of the same; the shaft 13 having a trunnioned connection with. said segmental sheave. This structure will be operated in a manner substantially if not exactly, similar to that described with referonce to the structure illustrated in Figs. 1, 2 and 3; a pulley 15", being formed integral with the segmental sheave and having a cord or chain 15, attached thereto in the usual manner for operation by the attendant, which cord will pass around theguide wheel 90, in the usual manner.

The cord or chain 15 passes from the pulley 15 around a guide wheel or idler 90, disposed adjacent the front of the main frame; thence extending to operative means (not shown) adjacent or convenient to the driver of the harvester whereby it may be readily operated at the desired time to trip the basket connection and permit the latter to lower and deliver a shock.

The wheel 25 hereinbefore referred to is loose on the shaft or axle 3, so that when the clutch 26 is out, said wheel will remain idle during any movement of the shocker. In the present instance, the clutch carries the usual yoke member 91, to. which is pivotally connected one arm 92 of a bell crank lever 93, ournaled in a bracket 94L, carried by the frame; the opposite end 95, of said lever being connected to a rope or cord 96 passing around a guide or idler pulley 97, and thence extending to suitable operative means mounted adjacent the driver or operator of the harvester. The clutch is of such a char acter that it must be held in operative po sition by pulling the cord 96; holding of the same being effected by suitable means adj acent the operator (not shown). ld hen this retaining means for said cord 96, is released, the clutch will automatically release itself upon continued movement of the shocking device.

' Formed integral with the iub 40, having the hollow stem i1, is a housing in which the rack 44:, is free to slide; such housing being slotted in the side for movement of a projection 46, carried thereby, which projection is pivotally connected to a rot l7, the outer end of which is universally connected at 48, to the rock sl La, carrier by the vertical frame 18, so that as movement is imparted to the rod or shat 35, swing the same from the platform to delivery position, andvice versa, the rod 4L7, will automatically operate the melt 4a, and thereby turn the gear wheel 42?, and effect the operation of the parts cont-rolled thereby.

In the operation of picking uptiic bundles, the fingers 50, engage the same on the platform 34, passing into the l m (see Fig. 9), and upon continued 1 of the bundle-grasping mechanism in the downward direction, the hook arms 56, con;- tact with the platform and. release themselves so that the spring 66, may cause them to grasp the bundles. In thisact, the bundles are brought together at one end of the same, while their opposite ends are spread apart, (see Fig. making it substantially easy for them to slide into the basket on both sides of the central partition of the basket after they have been reversed, (see it will be understood is being moved by the vertically movable that when the rod member 88, down the. rigntshandside ofthe slot 87, in the plate 20, that the sleeve 60, wi l slide on said rod 3", and elongate the spring 66, thereby placing the same under tension for the necessaryroperation of the hook-arms 56, when they are brought t bundle-gripping position.

\Vhilefwe have shown a certain arrangement of gearing whereby the bundle-hen dling device maybe operated, it'will be understooo that any gearing interposed between themain driving shaft and in opera; tive engagement" with the wheel 25, or its equivalent may be .employed to impart proper motion to the i vertically movable member 33, and thereby actuate the rod or shaft 35, to the end of which the bundlegrasping means are connected.
